We have a LOT of nuclear weapons in Europe. This is no secret. France, for instance, is a nuclear power as is the UK and we have nuclear stuff over there as well. If one goes off then I suspect we will have to respond in kind just to prove our point.

Perhaps somebody in Russia can stop it all but I have no idea who that might be. It seems, from all the reports, that the majority of Russians fully support Putin. Their military is not very good, their equipment hasn't been updated for a very long time, etc. I read a report that said that Putin and company has been looting so much money that there has been none left to update their military and poverty is growing by leaps and bounds but most continue to support the guy who is causing all the problems.

Everything said - the question isn't what's gonna happen its when is it gonna happen? The real question is the 'what' part of that sentence.
